hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal.
Drive immediately to an authorized Audi dealer
or authorized Audi Service Facility to have the
malfunction corrected.
A pulsing in the brake pedal indicates that the
system is acting to stabilize the vehicle.
Anti-Slip Regulation (ASR)
All-wheel drive: too hot. Please adapt driv-
ing style. See owner's manual
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
The transmission temperature has increased sig-
nificantly due to the sporty driving manner. Drive
in a less sporty manner until the temperature re-
turns to the normal range and the indicator light
turns off.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
Sport differential: temperature too high.
Please adapt driving style
In extreme cases, EDL automatically turns off to
keep the brake on the braked wheel from over-
heating. The vehicle is still functioning correctly.
EDL will turn on again automatically when condi-
tions have returned to normal.
The transmission temperature has increased sig-
nificantly due to the sporty driving manner. Drive
in a less sporty manner until the temperature re-
turns to the normal range and the indicator light
turns off.
Selective wheel torque control
WARNING
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Contact an authorized Audi dealer or author-
ized Audi Service Facility if the sport differen-
tial is faulty or malfunctioning. The repair
must be performed by trained personnel us-
ing the correct oil in order to ensure safety.
Power steering
The ESC can also support vehicle stability
through steering.
Electronic Stabilization
Control (ESC)
WARNING
Description
– The ESC and its integrated systems cannot
overcome the limitations imposed by natu-
ral physical laws. This is especially impor-
tant on slippery or wet roads. If the systems
begin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided cause
you to take risks. This could increase your
risk of a collision.
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations, such as if the vehicle is oversteering or
understeering, or if the wheels are spinning.
The brakes are applied or the engine torque is re-
duced in order to stabilize the vehicle.
The following stabilization functions are inte-
grated into the ESC, among others:
– Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
Anti-Lock Braking System (ABS)
ABS prevents the wheels from locking when brak-
ing. The vehicle can still be steered even during
